English C1 vocabulary: precision, register and nuance
Advanced vocabulary is not a contest to choose the longest word. At C1, the useful question is whether an expression conveys the right meaning, degree of certainty and tone for your audience.
Compare words in complete sentences
“Suggest”, “demonstrate” and “prove” do not make the same claim. Compare what each verb says about the evidence. Also notice whether an expression belongs in an informal conversation, a report or an academic discussion.
Record collocations and the context in which you found them. A synonym list without examples can hide differences in grammar, register and strength.
Match the strength of the claim to the evidence
Try revising a claim instead of simply replacing a familiar word with an advanced one. Ask what the reader can reasonably conclude from the information available.
The findings suggest a connection between the two factors, but they do not establish a cause.Turn reading into precise output
Lexiego can support repeated exposure and contextual word review. Add your own summaries and feedback on writing or speaking when those skills are part of your goal. A vocabulary exercise is not a certified C1 assessment.
- Read a passage and identify its argument.
- Select an expression whose nuance matters.
